Computer was fine, now is having lag spikes

[evilchaseofdoom]

My computer was fine for the longest time, and now is randomly having lag spikes. Since it first started I have: ran CCleaner, updated my drivers, cleaned out my fan in my laptop, bought an additional fan for my laptop, ran malware bytes and hitman pro. I also havent downloaded anything recently that I could think of and my CPU useage isn't crazy high. The only program that exceeds graal when it is open would be McAfee, but ive had that for a while. Any ideas?
